The medium GI green Classic Messenger Bag from Timbuk2 is designed to hold your 15" laptop plus accessories. Inside, a separate slash pocket protects your computer from coming in contact with any other item in the bag. The exterior has an organizer panel for quick access items while the interior features various organizer pockets for accessories and small items. An interior water bottle pocket is also provided. The Napoleon side entry zipper pocket is located under the front flap, and holds small, quick-access items. The bag also features a vista loop for attaching a blinky light.

Access to the interior is via two female snap connectors underneath the large front flap that mate with the male connectors on the bottom of the bag. These plastic female connectors also feature compression straps that tighten the closure providing a more secure seal. A non-removable, adjustable shoulder strap features a double loop cam buckle for rapid length adjustment. The strap also features an airmesh pad for breathability, while the low profile top grab handle provides portability.

The bag is made from polyester canvas and features an interior waterproof thermoplastic polyurethane liner. The corner flaps can be folded inwards to provide additional protection from water seeping in.
